From mboxrd@z Thu Jan 1 00:00:00 1970 From: Thomas Abraham Subject: [PATCH v2 0/2] Add device tree based lookup of boost mode frequency Date: Fri, 7 Feb 2014 20:49:00 +0530 Message-ID: <1391786342-11812-1-git-send-email-thomas.ab@samsung.com> Return-path: Sender: linux-pm-owner@vger.kernel.org To: linux-pm@vger.kernel.org, devicetree@vger.kernel.org, linux-arm-kernel@lists.infradead.org Cc: rjw@rjwysocki.net, linux-samsung-soc@vger.kernel.org, kgene.kim@samsung.com, t.figa@samsung.com, l.majewski@samsung.com, viresh.kumar@linaro.org, thomas.ab@samsung.com List-Id: devicetree@vger.kernel.org Changes since v1: - Boost mode frequencies are specfied as a set of frequencies instead of specifying them as OPPs. Thanks to Nishanth, Lukasz and Rob for the feedback. Commit 6f19efc0 ("cpufreq: Add boost frequency support in core") adds support for CPU boost mode for CPUfreq drivers. To use the new boost mode, CPUfreq drivers have to specify the boost mode frequency and voltage within the CPUfreq driver, which is the case for Exynos4x12 CPUfreq driver. But for CPUfreq drivers which obtain the OPPs from cpus node, this patch series adds support to specify boost mode frequencies in the cpu device tree node. This requirement came up when Lukasz pointed out the regression caused by the Exynos CPUfreq driver consolidation patches.
